Hi @MMazurski hope you are doing great.
The first thing that comes into mind is
do you have the automated lifecyclestage update on?
Why am I asking this?
Because if you have this on
when a contact has an associated deal, it changes the lifecycle stage from lead to “opportunity”.
And once a deal is closed won it changes to “customer”.
So maybe the values you need to see for your report
are “Opportunity” and “Customer”, and not lead.
Just checking the obvious-not-so-obvious.
